Misperceptions about 2D imagers are changing fast, which is why 2D imagers are the fastest-growing category of bar code readers. Only a few years ago 2D imagers were (wrongly) considered a niche technology mostly used for reading 2D bar codes. Now they are becoming the technology of choice for most bar code applications, and lasers are on the way to becoming a niche technology. The reasons: 2D imagers are as fast or faster than laser scanners, can read all the same bar codes as lasers plus 2D symbols that lasers can’t, and can do much more.
